[Gambas-bugtracker] Bug #2733: ListView - Scrolling at the moment of Selection

Comment #2 by Claus DIETRICH:

Meanwhile I found a way to reproduce the issue reliably:

1. Clicking on another app, so that the web-radio-app looses the focus.
2. Hovering with the mouse over the ListView and scrolling with the mouse wheel
3. Selecting a list-item at a very different position

With this the ListView always selects an item in the scroll area which was
displayed just before it lost its focus. So the control assumes that the list
is still in same position as it was when it lost the focus.

The scroll-event however is firing well and the ScrollY-Value is updated - no
matter whether the control has the focus or not. But it seems that the mouse 
assumes a different (not updated) position when the control was scrolled
without having the focus.

Best regards
Claus
